The recent surge of deaths — including three on January 19 — has garnered the attention of Manhattan Borough President Scott Stringer, who wants an in-depth investigation into subway-related casualties by the Office of the MTA Inspector General.

In a press release, Stringer called for an analysis of safety programs used in transit systems around the world, including platform barriers.

After an attempted suicide by train in Brooklyn on Sunday morning, Stringer renewed his call for an investigation, saying, "This is a troubling and dangerous trend with serious implications for the millions of commuters who ride the subway each day."

The Office of the MTA Inspector General did not reply to a request for comment.
